我有一些R代码用ggmap在地图上绘制数据.它上周工作正常.但是,现在当我运行该行来获取地图时:
emap <- get_map(c(-2.503704,43.18735),zoom=9,maptype="roadmap",color="bw")
我收到以下错误:
Error in gzfile(file, "rb") : cannot open the connection
In addition: Warning message:
In gzfile(file, "rb") :
cannot open compressed file '/var/folders/2w/2wSOAL2LFUC+2QkRaR1wI++++TI/-Tmp-//Rtmpj0TMx5/ggmap/index.rds', probable reason 'No such file or directory'
我搜索了这个论坛和网络,但找不到任何其他线程讨论此错误.
任何帮助深表感谢.此致,Noelia
